Extratropical cyclone, remnant low, tropical disturbance, or monsoon depression

A tropical disturbance wave near the Philippines were detected to be developing and PAGASA quickly upgraded it to Tropical Depression Hanna on September 27. PAGASA upgraded it into a tropical storm the next day. It made landfall in central Luzon early on September 29, and at the same time JMA upgraded the developing system into a tropical depression, ^[1] while JTWC started a TCFA shortly thereafter at 09:00 UTC on the same day. ^[2] JMA declared the system Tropical Storm Lekima on the next day. ^[1] It continued to strengthen and Lekima was upgraded into a severe tropical storm on September 30 by JMA and would remain as such until landfall. ^[1] Meanwhile, JTWC upgraded Lekima into a typhoon in October 2 and it would also remain as such until landfall. ^[2] Lekima was the largest newborn tropical system on record by diameter at 1700 km at the time before being beaten by Tropical Storm Kompasu 14 years later by 200 km. ^[3]

Lekima made landfall on Quảng Trạch District, Quảng Bình Province, Vietnam at 12:00 UTC in October 3 as a severe tropical storm. JTWC published the last Tropical Cyclone Warning later that day at 18:00 UTC while downgrading Lekima into a tropical storm, and JMA followed the suit at the same time. ^{[1] [2]} On the next day, Lekima weakened into a tropical depression over Laos by JMA, but JTWC did not follow suit. ^{[1] [2]} Lekima dissipated over land on October 5. ^[1]

Preparations and impact

Philippines

Hanna brought heavy rains to Luzon causing a landslide that killed eight people, including three children, in Ifugao province, while another person was found dead in Quezon City. ^[4] Torrential rains also caused landslides, flooding, infrastructure damage, and disruption of transportation service in other parts of the country. ^[4] A Office of Civil Defense administrator said that several people had to leave their homes, mainly in the north of the country, and that heavy rains damaged roads and bridges, as well as damaging the local agriculture. ^[5]

China

Over 100,000 people were evacuated in southern China as the storm approached, six flights were cancelled ^[5] and more than 20,000 fishing boats were recalled back to the harbors. ^[6]

Vietnam

On October 3, Lekima made landfall in Vietnam. Due to the impact of Typhoon Lekima, a weather station in Kỳ Anh (Hà Tĩnh) recorded sustained winds of 130 km/h (81 mph), while another station on Hòn Ngư Island (Nghệ An) recorded sustained winds of 94 km/h (58 mph). Rainfall from 19:00 on October 1 to 01:00 on October 4 (UTC+7) in provinces (or municipalities) from Hà Tĩnh to Quảng Nam generally ranged from 200 mm (7.9 in) upwards, with some locations recording over 500 mm (19.7 in) of rainfall. The lowest sea-level pressure measured in Ba Đồn (Quảng Bình) during the storm was 975.5 hPa (28.81 inHg). ^[7]

Over 400,000 people were reported to have been evacuated in Vietnam as the storm approached. ^[8] Upon arrival, associated rains caused heavy damage as about hundreds of houses were destroyed, more than 6,000 houses were washed away by the storm and 52,000 others were damaged. ^[9] Many regions were affected by the storm, causing heavy damage to the local agriculture. More than 10 million people were affected by the storm. ^[8] According to official statistics from the Viet Nam Disaster and Dyke Management Authority, Typhoon Lekima and the subsequent flooding resulted in 88 fatalities, 8 people missing, the destruction or sweeping away of 1,853 houses, and partial flooding or damage to 111,170 homes. Additionally, 8,849 hectares of rice fields and 18,220 hectares of other crops were completely lost. Various other types of damage were also reported. The total economic loss caused by the typhoon was estimated at 3,216 billion VND (approximately US$199.3 million). ^[10]
